# 这个循环,每次取出一列数据,然后用均值来填充 for i in movie.columns: if np.all(pd.notnull(movie[i])) == False: print(i) movie[i].fillna(movie[i].mean(), inplace=True) 6.2.3 不是缺失值nan,有默认标记的 直接看例子: 数据是这样的: # 读入数据 wis = p

You can useisin()with multiple columns in pandas. When usingisin()with multiple columns, you typically provide a dictionary where keys are column names, and values are lists of values to check for in each respective column. Can I use isin() with a single value?
# Multiple row and column selections using iloc and DataFrame 使用iloc和DataFrame选择多个行和列 data.iloc[0:5] # first five rows of dataframe 数据帧的前五行 data.iloc[:, 0:2] # first two columns of data frame with all rows 数据帧的前两列,所有行 ...

To select multiple columns, use a list of column names within the selection brackets []. dataframe[]可以接受series关系表达式(其实该值还是series),pandas提供了一些优化的方法来代替关系表达式的符号) 例如: notna() isin() loc与iloc 对dataFrame的筛选 ...
